Bio: The Cell -Vocab
Body Structure & Function
| Question | Answer |
|---|---|
| Organelles | A specialized sub-unit within a cell that has a specific function. Usually separately enclosed within it's own lipid layer. IE: Nucleolus, Nucleus |
| Cell Membrane | The membrane that forms the outer boundry of a cell. Made up of phospholipids, protein, cholesterol, with carbohydrates on the outer surface. |
| Bilipid Mosaic Model | |
| Cytosol | (ICF) the liquid found inside the cells. A complex mixture of substances disolved in water. |
| Nucleus | Control Center of a Cell. A membrane enclosed organelle found in eukaryotic cells. Contains most of the cells genetic material. Maintains the integrity of the cells genes. (regulates gene expression) |
| DNA | A neucleic acid that contains the genetic instructions used in the developement & functioning of all living things & some viruses (a blueprint) |
| mRNA,Messenger Ribonucleic Acid | a molecule of RNA encoding a chemical blueprint for a protein product. |
| tRNA, Transfer Ribonucleic Acid | transfers a specific active amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation. |
| rRNA, Ribosomal Ribonucleic Acid | Central component of a ribosome. the protein manufacturing machinery of all living cells. |
| Transcription | (RNA synthesis) the process of creating an equivalent RNA copy of a sequence of DNA. |
| Translation | First stage of protein biosynthesis. (part of the overall process of gene expression) |
| Mitosis | Process by which the body grows & dead cells are replaced. A continuous process. (Prophase, metaphase, anaphase & telophase) |
| Cytoplasm | Part of the cell that is enclosed within the cell membrane. |
| Nucleoplasm | a special type of cytoplasm found in the nucleus. |
| ER (Rough & Smooth) | An eukaryotic organelle that forms an interconnected network of tubules, vesicles & cisternae within the cells. |
| Mitochondria | Cellular power plants. A membrane enclosed organelle. Generates most of the cells supply of ATP (Adenosine Triphosphate) |
